SPECIFICATION forming part of Letters Patent No. 385,919, dated July 10,1888.

Application filed February 23, 1888. Serial No. 265,010.

To all whom it may concern.-

Be it known that I, ABRAHAM DAY, a citizen of the United States,residing at Bloomfield, in the county of Essex and State of New Jersey,have invented certain new and useful Improvements in Portable Ovens; andI do hereby declare that the following is a full, clear, and exactdescription of the same, ref' erence being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

This invention relates to certain new and useful improvements inportable ovens, and the novelty resides in the peculiar combinations andthe construction, arrangement, and adaptation of parts, all as morefully hereinafter described, shown in the drawings, and thenspecifically pointed out in the claims.

The invention is clearly illustrated in the accompanying drawings, inwhich Figure 1 is an end View of my improved oven. Fig. 2 is a frontView of the same with the door shown open to disclose the shelves, andFig. 3 is a central vertical section of the same.

Referring now to the details of the drawings by letter, A designates theoven entire divided into two com partmentsan upper and a lower onebymeans of the partition a,preferably of firebrick.

B is the heater, made removable and designed to be placed in thelowercompartment, as shown. This heater has a perforated partition, b, abovethe ash-pan, and preferably provided with a cover, 0, as shown.

C are transverse slats or bars secured within the lower comparti'nentabove the heater, and are designed to support a broiler when desired.

D is a door sliding in suitable guides,'d, and is designed to be raisedto disclose the interior of thelower compartment. It is provided with atransverse sliding door to admit cool air into the lower compartmentwhen neces sary.

\Vithin the upper compartment are arranged a plurality of shelves, E,which are constructed as shown in Fig. 3. Each shelf is composed of twothicknesses with a space between them, and are so arranged that theheated air is forced to pass upon four sides of the space between eachtwo shelves, as indicated by the arrows in Fig. 3. Upon one side of theupper compartment, between the ends of the shelves and the outside wallof the oven, is a flue, F,

communicating with the lower compartment and with the space 6 at the topof the upper compartment, so that the hot air from the heater in thelower compartment will pass up through said fine and around thesub-compartnients in the upper chamber, and finally out of thestove-pipe G, as clearly indicated by the arrows in Fig. 3. At the topand bottom of the upper compartment the double thickness of the materialprevents much loss of heat.

His a door to the upper compartmeut,hinged at f.

It will be observed that by the construction shown and above describedthe various subcompartments can be readily heated, and will retain theheat for a long time.

WVhat I claim as new is 1. A portable oven consisting of twoconipartments, the lower one provided with a heater and with transverseslats 0 above said heater, and the upper one subdivided by hollowshelves communicating with the lower compartment and with each other,substantially as described.

2. In a portable oven, hollow shelves arranged within the same above theheater,communicating with each other, and a line, F, between one end ofthe shelves and the outer wall of the oven,and affording communicationbetween the heater-compartment and the uppermost of the shelves,substantially as shown and described.

The portable oven described, consisting of the shell or case, thepartition a, dividing the same into an upper and lower compartment, aplurality of hollow shelves arranged within the upper compartment, theflue F upon one side of the upper compartment, and communicating withthe lower compartment and with the space 0 at the top of the uppercompartment, and the pipe G at the lower end of the upper compartment,the said shelves communicating with each other and with the flue F andpipe G, and having a space for hot air on all sides thereof,substantially as shown and described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

ABRAHAM DAY.
